Not true. It is a *myth* that has propogated thru these lists so many
times that it *sounds* true. If it were true, gentoo users would need
to reinstall their OS every time a toolchain package was updated.

As long as you are upgrading the toolchain packages (not downgrading)
everything should be ok, especially if they have the same major (and
minor version?) as the package that is already installed. The only
care that needs to be taken is: If the soname of a library has
changed, that library should not be removed until the executables
linked to that library are recompiled.
